UNITED STATES JOHN H. HOBSON, OF SULPHUR SPRINGS, ARKANSAS.

BLOW AND FLUE CLEANER.

Application filed October 18, 1926. Serial No. 142,385

This invention aims to provide a device which, with minor alterations, may be used, at the will of an operator, as a flue cleaner, or as a means for producing a forced draft, in a stack or elsewhere.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view which wall appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the preciseembodiment of theinvention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings Figure 1 shows in section, a device constructed in accordance with the invention,

parts being in elevation, the device being set,

up for use as a flue cleaner;

Figure 2 is a cross section on the line 22 of Figure 1;

Figure 3 is a longitudinal section showing the device set up as a blower.

Referring to Figures 1 and 2, the device is shown as comprising a tubular body 1. The numeral 2 marks a funnel-shaped apron having a cylindrical neck 3 that is threaded at 4 on one end of the body 1, the body being provided, near to the said end thereof, with an internal spider 5 the hub of which is marked by the numeral 6. A T couplin 7 is disposed adjacent to the apron 2 and as a lateral nipple 8. A nozzle 9 is securely mounted in the hub 6 of the spider 5 and is extended into the body 1, one end of the nozzle being mounted in one end of the coupling 7. A member 10, to wit, a steam or other fluid-pressure conduit, is mounted in the opposite end of the coupling 7, and a member llis mounted in the lateral nipple 8, the member 11 being a projecting solid closure, of such length that it may be used as a handle. The nozzle 9 includes a reducer 12 carrying a tip 14.

In practical operation, the device is manipulated by means of the handle 11, and the body 1 is inserted into the fine to be cleaned, until the apron 2 engages the end of the flue. Then, when steam or other fluid under pressure passes from the conduit 10 through the nozzle 9 and its tip 14, air will be drawn in through the apron 2 and through the body 1, the blast thus created being of manifest utility in cleaning out the flue.

In Figure 3, parts hereinbefore described have been designated by numerals previously used, with the suflix a The projecting solid closure is a screw plug 15 threaded into the outer end of the T coupling 7, the fluidpressure conduit 16 being mounted in the lateral nipple 8. The device shown in Figure 3, when placed in a stack, or in any other place where a draft is desired, will'create a blast or draft, in a way which will be understood readily by those who are skilled in the art.

lVhat is claimed is i A combined blower and flue cleaner comprising a tubular body of a common diameter from end to end and provided at one end with a funnel-shaped apron, the tubular body having an internal spider disposed closely adjacent to one end of the body, a T coupling disposed adjacent to the apron and having a lateral nipple, a nozzle mounted in the spider and extended into the body, one end of the nozzle being mounted in one end of the coupling; a member in the other end of the coupling, and a member in the lateral nipple of the coupling, one of said members being a fluid-pressure conduit, and the other of said members being a projecting solid closure.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.

JOHN H. HOBSON.
